Our app seems to run just fine on Tomcat 6/Java 6 for about 20 users for around 10 minutes, and then Tomcat just stops serving requests.
After about 10 minutes, it resumes as though nothing ever happened. We tried this on Java 5, Tomcat 5, and we had the same problem. It isn't the displaytag (huge list) problem mentioned in another appfuse thread - we're not displaying any huge lists (no more than 20 items, with 5 columns). No database contention, nothing that shows in the logs. We thought it might be gc'ing, but it's just not using that much memory. Does anyone have any ideas?
